Name change for this one.
My 19 year old sons best friend since he was 10 has been charged with SA against another girl in their friendship group at a house party. He blocked her in a room after getting her drunk and was pressuring her for things and kept grabbing at her and trying to slide his hand up her leg whilst telling her she knew she wanted to do it etc. She was upset and asking to leave and he wouldn't let her leave the room until the friend group including my son realised they were both missing and went to find them to check they were ok.
She came out in tears, told everyone what happened. My son took his best mate off and ended up punching him mid way through a chat as he apparently saw nothing wrong with what he'd done and was using derogatory language towards her...saying she was a slag etc.
My son and their other M/F friends have obviously rallied round the girl and she has a wonderful family who are looking after her.
My son told me and his father who doesn't live with us what had happened separately.
His father turned round and told him he should have stuck up for his mate (you can see why our relationship ended in this one sentence).
After a long string of things like this with his dad (that is already in counselling for) he's decided to cut contact with him. Plus his best mate and the friendship group has absolutely disbanded over the last week with people taking sides.
My son is very upset he's lost his best friend and finally decided to cut out his dad but he's also adamant its the right decision for both.
Any advice on how to handle this?
AIBU if I just let his relationship with his father dwindle out now?
